XNITTING-YARN PACKAGE.

Specification of Letters Patent.

Patented Feb. 6, 1917.

Application tiled April 7. 1915. Serial No. 19,727.

To all whom z't may concern:

Be it known that I, JACOB K. ALTEMUS, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Knitting-Yarn Packages, of which the following is a specification.

This invention is an improvement in knitting yarn packages for supplying knitting and other textile machines, and its purpose is to produce a package so built as to contain a greater quantity of material and deliverits contents more freely than packages usually employed for a like purpose. This is accomplished by a novel system of winding which is fully illustrated in the accompanying drawing, in which:

Figure 1 is a diagrammatical showing of the yarn layers on a foundation cone, and Fig. 2 is a diagrammatical showing of the first ascending and descending foundation layers wound on the cone.

In practising the invention, a modified form of the type of machine illustrated in the Brooks Patent No. 1,120,438 is employed, wherein the yarn is delivered by a yarn delivery guide which ascends to lay the first ascending layer and then descends to lay the first descending layer, whereupon the yarn delivery guide steps up a point and lays the next ascending and descending layer-set and so onuntil the cone is completely filled with arn.

In Fig. 1, reference characters l, 2, 3, 4, 5,.

6, 7, 8, 9, indicate layer-sets occurring at selected intervals in the body of the yarn package. It will be understood, that the layer-sets are more numerous than indicated in Fig. 1, but' the selected layer-sets indicated by these reference characters will suffice to give a clear understanding of the general build of the package and for clearness, the indicated layer-sets will be referred to as if they were the only ones present in the package. The first layer-set 1 extends from elevation A to elevation A', and the succeeding layer-sets 2, 3. 4, 5, 6, 7, 8, 9, extend respectively from elevations B. C, D, E, F, G, H,- I. to elevations B', C', D', E', F', GTI-l', I'. The layer-sets vary as to length` but the distance between the elevations A and A' known as the traverse is the same as that between the elevations B and B' or C and C', and so on. The distance between each elevation A--B, B-C,

CD, and so on to H-I, is known as the again.

Each layer-set 1 to 9 inclusive actually comprises two layers, one ascending and the other descending, according to the showing in Fig. '2, and both being coincident as to their starting and finishing points. The threads of the ascending layer are in this view shown by unbroken lines 20, while, for clear differentiation therefrom, the threads of the descending layer are shown by broken lines 30.

The threads or coils 20 are laid ascendingr upon the foundation cone 40 commencing at initial elevation A and rising to elevation A', the said threads or coils being laid closest together near the elevation A and gradually becoming spaced farther apart until the elevation A' is reached. The threads or coils 30 are then laid upon threads or coils 20 commencing at elevation A' and descending until elevation A is reached, the said threads or coils 30 being laid farthest apart near the elevation A' and gradually becoming spaced closer together as the elevation A is approached'. lVllile in Fig. 2, only one up and one down layer 20 and 30 respectively, extending from elevations A to A', are illustrated, it will be understood that the layer-sets occurring between eleva tions B, C, D` E, F, G, H, I, and B', C', D', E', F', G', H', I', respectively, comprise similar layers except that 'each Successive layer-set is slightly stepped up a point as from elevation A to B, or B to C, and so on.

The ascending layer has in its length approximately twenty-seven winds vor coils 20, while a considerably less number of winds or coils 30 occur-in the descending layer, only approximately fifteen in the latter being present. This gives ratio of substantially two to one, though not exactly, which ratio should be substantially obtained regardless of thc actual number of winds or coils in the two layers. As a consequence of this ratio. each descending wind or coil 30 overlays and binds. in most instances, at least two of the underlying ascending winds or coils, and becauseof the large angle of intersection more 'effectively prevents the winds or coils of succeeding layers from producing an underwind than would be possible were there as many descending winds or coils 30 as in the ascending course Q0. Moreover. it will be observed that the points at which the descending threads 30 intersect the ascending ltween the threads or coils of each layer, the

lower contour of the yarn package would be straight sided, but with the irregular and "ariable spacing, with the greatest lamount. of yarn in the lower portions of the several layer-sets, this lower contour becomes curved as indicated b v reference numeral 50, which is to be explained as follows: The first layer-set 1 is parallel with the side of the foundation cone. The second selected layer-set Q, being stepped up to start at ele 'ation B, because of its bulk increasing toward its lower end, lies at a slight angle to the side of the cone and layer-set 1,` its upper end falling over the upper end of layer-set 1 and against the cone. bending on line X-X as is the case with the successive layer-sets which intersect such line X-X. The third layer-set 3, likewise, because of its tapering bulk, lies at a greater angle below the line X-X to the cone side than the preceding layer-set "2. Substantially at the line X-X, the. layer-set 3 bends to fall over with the bending upper end of layer-set 2, but slightly closer thereto near the cone than at the line X-X, and this is true of the upper ends or portions of all the layersets above the line X-X.

0n the bending line X-X, the distance between the selected layer-sets 1 and 2 is less than between 2 and 3, and this distance between the succeeding layer-sets increases outwardly. This is due to the fact that the layer-set 2 where it bends on the line X-X is not only comparatively lean itself, but bends over the leanest portion of layer-set 1, while the layer-set 7 where it bends on the line X-Xy is notlonlyapproaching its greatest bulk, approaching such, portion of the' layer-set 6.

It will also be noticed that the greatest angle of bend of the layer-sets on line X-X is near the cone, such angle gradually disappearing until the bend in layerbut bends over the fattest, or

set S becomes hardly apparent, and there heilig no perceptible bending in the final layer-set 9 because of its being entirely above the bending line X-X. This diminution of bending is the result of the ever increasing bulk below the line X-X upon the straight sides of the cone, the

other layers i) to 9 describe curved lilies, taking the general directions indicated by the lilies 1 to 9 of Fig. 1.

The advantages of this system of winding not only resides in the laying of considerably more yarn on the foundation cone, but in a great reduction in the drag of the varn against the bod \v yarn on the ott-take.' The qlnck descent of the descendlng layer` causes rapid unwinding of the threads thereof on the otf-take, and, moreover, these descending threads bind the underlying coils in a way to render underwinding impossible.

'hat is claimed:

1. A knitting yarn package including a conical foundation having wound thereon successive coniform layers all of uniform traverse and uniform gain, the spirals of the layers being laid closer together at the base than at the top portions of the layers.

Q. A knitting yarn package including a conical foundation having wound thereon successive conifonn layers of uniform traverse and uniform gain, the spirals'being gradually closer together at the base than at the top portions of the layers.

3. A knitting yarn package incluozlin'gv a. conical foundation having wound thereon successive progressive and retroprogressive coniform ylayers of uniform traverse and gain. the spirals of said layers being closer together at the base than at the top portions of said layers, the progressive layers having more spirals than the retroprogressive layers.

In testimony whereof I atlix my signature in presence of two witnesses.

JACOB K. ALTEMUS.
